Stoptech 127.33137R Disc Brake Rotor - Rear Right

StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors Overview

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors (Part Number 127.33137R) are engineered for Audi and Porsche vehicles, including models such as the Audi A4, A5, A6, A7, Q5, and Porsche Macan. These rotors provide enhanced braking performance through a vented, slotted, and cross-drilled design that improves heat dissipation and reduces brake fade.

• Cross-drilled and slotted surface for improved cooling and debris removal
• Vented rotor design with pillar-style vanes for efficient heat dissipation
• Coated hat finish to resist corrosion and extend rotor life
• Floating disc mounting for better thermal expansion management
• Compatible with ABS systems (ABS tone ring not included)
• Precision fit for Audi and Porsche models with 5 lug holes and 330 mm outside diameter

Detailed Product Features and Specifications

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors feature a nominal thickness of 21.8 mm and a discard thickness of 20.0 mm, ensuring durability and reliable performance throughout their service life. The rotors measure 330 mm in outside diameter and have an overall height of 36.2 mm. The vented design incorporates pillar-style vanes that enhance airflow to reduce heat buildup during aggressive braking. The rotor hat is coated to protect against rust and corrosion, maintaining structural integrity and appearance over time. This rotor uses a floating disc mounting system, which allows for better thermal expansion and reduces the risk of warping under high-stress conditions.

StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors Product Line

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line is designed to offer improved braking performance for sport and performance vehicles. This product line focuses on enhanced heat dissipation and consistent braking under demanding conditions by combining cross-drilled holes and precision-machined slots. These features help to evacuate gases, dust, and water from the rotor surface, improving pad contact and reducing brake fade. The rotors are engineered to meet the specific fitment requirements of Audi and Porsche models, ensuring a direct replacement with no modifications needed.

Applications and Problem Solving

• Reduces brake fade during high-performance or spirited driving
• Improves wet weather braking by channeling water away from the rotor surface
• Minimizes brake dust buildup for cleaner operation
• Prevents rotor warping caused by excessive heat
• Enhances overall brake system responsiveness and pedal feel

Installation Notes and Tips

These rotors are designed for direct replacement on compatible Audi and Porsche models listed in the fitment. It is recommended to replace brake pads simultaneously to ensure optimal performance. Verify rotor thickness before installation and ensure the discard thickness is not exceeded. Proper torque specifications should be followed when mounting the rotor to avoid warping. Since the rotors do not include bearings or ABS tone rings, reuse existing components or source separately if needed.

Quality Assurance and Warranty

StopTech rotors are manufactured to meet or exceed OEM standards for fit, form, and function. The coated hat finish provides corrosion resistance to extend rotor life. While specific warranty details are not provided here, StopTech products typically come with a limited warranty against defects in materials and workmanship. Always consult the product documentation or manufacturer for exact warranty terms.
